"Ultimately what we want to do is change the culture of acceptance that these plays are ordinary and routine and an accepted part of the game," Alderson said. "The costs associated in terms of health and injury just no longer warrant the status quo."
The NFL reached a settlement last summer in a concussion-related lawsuit by former players for $765 million, and a group of hockey players sued the NHL last month over brain trauma.
Banned for life in 1989 following a gambling investigation, Rose insists Fosse was blocking the plate without the ball, which is against the rules. Fosse injured a shoulder, and his career went into a downslide.
"Since 1869, baseball has been doing pretty well," Rose said. "The only rules they ever changed was the mound (height) and the DH. I thought baseball was doing pretty good. Maybe I'm wrong about the attendance figures and the number of people going to ballgames."
Alderson said wording of the rules change will be presented to owners for approval at their Jan. 16 meeting in Paradise Valley, Ariz. Details must be sorted out, such as what should happen if a catcher blocks the plate without the ball.
"The exact language and how exactly the rule will be enforced is subject to final determination," he said. "We're going to do fairly extensive review of the types of plays that occur at home plate to determine which we're going to find acceptable and which are going to be prohibited."
Approval of the players' union is needed for the rules change to be effective for 2014.
"If the players' association were to disapprove, then the implementation of the rule would be suspended for one year, but could be implemented unilaterally after that time," Alderson said.
The union declined to comment, pending a review of the proposed change. Some players spoke up on Twitter.
